FAQ
Standard 100°C. Engineering 150°C. PEEK 250°C. Above PEEK requires metal.
Aluminum 200°C. Steel 500°C. Stainless 800°C. Inconel 700°C+. Tantalum 1500°C.
Plastic deflection under load at temperature. Lower than continuous service temp.
Glass fibers raise plastic HDT 30-50%. Higher service temperature possible.
Specify continuous service temperature. Allow safety margin. Material/process per spec.
ASTM D648 HDT. ASTM E831 thermal expansion. Per applicable.
